Application filed september 1 To all whom it may concern:

lie it known that I, Haney N. HAMLIN, a citizen of the United States, residing at Milo, in the county of Piscataquis and State ot Maine, have invented certain new and useful In'iprovenients in i tutoinatic Pay-Statidns; and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to lmPl'OVOIDGHiS in telephones and more particularly to pay stations therefor.

It has for its ohject. to facilitate or aid a person desiring to transmit a message, well as the telephone con'ipany in eliect ing the proper deposit and application of the coin for payment of such message over its line, and to carry out these ends in a simple, inexpensive and effective manner.

lVith these and other objects in View, the

invention consists of certain novel. feature-i of construction, combination and arrangement of parts, as will. be more fully de scribed and particularly pointed out in the appended cl-ain'is.

The accompanying drawing illustrating the preferred embodiment of my invention represents a diagranunatical sectional view thereof.

ln practicing my invention, 1 suitabl i ar-v range in the usual box or housing at a pay station along a telephone line a plurality or number of spring contact fingers l 2 and 3 suitably insulated and secured in position on a bracket 4, two of said lingers heing suh stnntially of the same length and the third extending some distance beyond the latter with its extended portion forn'iing a spring 5 and the free ends of each ot the other fingers having, platinum contact points 5. These fingers are suitably connected to wires (5, 7 and 8, respectively, 6 being the line wire,

7 leading to a battery and 8 being connected with the primary nieinher oi? an induction coil. i

A bell crank lever lOQis suitably ful Specification of Letters Patent.

pinion ll at the end of one arm which gears with a (forrespoiuluig pinion upon a lever l3 having its 'li-ee end extending into and operable within a chute 14- for the reso ception of the coin, said end of the lever 23 being adapted to he readily engaged by a coin as it passes down through said chute.

it will he noted that. a coin ii'iserted through the slot in the box above described passes down through the chute 1 i and en gages the end oi the lever 13 protruding into said chute and the-relay actuates said lever. When the lever it; is engaged and.

actuated by the coin, the interineshing pin- 7o ions 1 l and 12 will actuate the hell crank lever 10 to cause the tree end thereof to niove away from the insulated end 9 of the spring exlension 5 of fingerl which will permit said finger 3, by reason of the opposite linger and the latter to contact with the finger it, thus lorinirg a circuit by the aid of the wires (3, 7 and 8, and sending in a signal through a suitably 10- cated bell, which signal will be transmitted to the central otlice, and thus notify the latter of the proper depositing of the coin.

After the operation of parts, the lever 10, together with the lever 13 and their intergeared pinions, will resume initial position under the tension or pressure of a spring 15, suitably connected to the lever 10 andzto a fixed point, res iiectivcly, thus restoring the parts into position for a repetition of the operation above described. served that by means oil' the aforesaid coinhinalion and arrangement of parts certain disadvantages as lieretotpre experienced in connection with telephone pay stations are obviated in that as a party desiring to use the telephone is assured that the coin placed I in the chute for its reception in n'nihing payment l'or his message, will send in the rcquired signalwithout any possible failure of the same being noted at central ollice, and

that the said contrivance is capable of use ivholly independent oi the action of the receiver, and that the receiver is capable pf use, andot sending in the required signal also independent; oi l thi action ot the signal indicating the deposit. oi? a coin.

From the itoregoiug "lrscription, taken in ccumection with the accompanying drawings,

the construction and operation of the inven- 11W tion will be reaoily understood without requiring a more extei'ided explanation.
